Description
The present invention relates on a kind of eyeglass piece and remove block method and device, it is used for eye lens is adhered to the eyeglass cushion block (lensblock) that routine processing, grinding and the treatment facility of eye lens production are adopted.
The technology of preparation optical mirror slip or eye lens starts from unprocessed or half-finished glass or glass lens blank.Usually, half-finished lens blank has the front and the unprocessed back side of finishing polishing.Fall material by grinding back surface, produce required correction quality requirement from lens blank.Subsequently, the surface that is endowed the correction quality requirement is polished, and possess final required profile, form optical mirror slip or eye lens whereby through finishing through the peripheral edge of the lens blank of handling like this.Lens blank can be plastics or glass lens blank.
Be necessary to keep safely lens blank on aligned position accurately and on the eyeglass cushion block in these various processing operating periods.This program often is called as " piece on the eyeglass " (lens blocking).
Adopt various materials that lens blank is fastened to the eyeglass cushion block before this.These materials comprise glue, pitch and low temperature fusible metal alloy.Use glue and pitch except meeting is very dirty, also to suffer to re-use substantially or expendable shortcoming.Eliminated some shortcoming of using in these shortcomings that glue and pitch ran into though use the prior art of low-temperature metal alloy, yet, these metal alloys in its preparation and the use in reclaiming all cause significant environment and health hazard, especially because these alloys the most often are during by metals such as for example cadmium, tin, lead and bismuths.In these metals, plumbous and cadmium is tool toxicity.Lead is stronger protoplasm poison, and can by ingest, suction and skin absorbs and enters human body.Cadmium poisoning is similar to lead on many modes, and enters human body in the mode identical with lead.Be similar to lead, cadmium accumulates in liver, kidney and the bone.Be used to prepare these a little alloys and in order to realize therefore making the workman be exposed to rugged environment and health hazard as the program of the removal process of the material that lens blank is fastened to the eyeglass cushion block once more it.Often stand the powder of sintering and Technology for Heating Processing or the formation that particle metal is finished these alloys by use.The cigarette and/or the dust particle of these metals are released in the ambient atmosphere, and then the people who prepares these alloys is produced environment and health hazard.There is identical harm for those people that attempt to reclaim with block of material on the low-temperature metal alloy of crossing.
For overcoming these problems, developed organic low shrink-down material as block of material on the eyeglass.
Patent US 6,036,313 under " 3M Innovative Properties " exabyte has disclosed the example that is suitable for carrying out with thermoplastic the compound group of piece on the eyeglass.
The last block composition that is disclosed has many advantages that are better than the conventional metals alloy material.For instance, block composition is non-toxicity, Environmental security on the eyeglass, and is preferably biodegradablely.Described material preferably can use and can reuse with existing treatment facility.Spendable eye lens cushion block can comprise block composition on the thermoplasticity through solidifying the quality body.Last block composition can comprise homopolymers (homopolymer) or the copolymer (copolymer) of 6-caprolactone (epsilon-caprolactone), and preferably have at least 3,000 number-average molecular weight (number average molecular weight), under 21 ℃ the average bending modulus of 69MPa (MPa) (mean bending modulus) at least, or under 21 ℃ the average flexural strength of 1MPa (mean flexural strength) at least.Composition is down solid at 21 ℃, and has enough low fusing point or softening point, makes can not damage lens blank when the fusing point of composition or softening point following time are adjacent to the eye lens blank with its placement.Composition also has enough adhesion strengths of lens blank or lens blank coating or band are had in mind with fixing during production routine uses eyeglass.
Described document also discloses piece external member on the eye lens, and it comprises block composition and optional lens blank band or coating and/or preform substrate cushion block on the thermoplasticity.For instance, preform substrate cushion block comprises the forward part with negative taper peripheral edge.Preform substrate cushion block easily keeps block composition on the thermoplasticity, also can be from its separation after using.But the lens blank band is conformal, and comprises the copolymer backing (polymer backing) with polarity and nonpolar half one.By regulating the ratio of polarity and nonpolar half one, can regulate adhesion strength to block composition on the thermoplasticity.
This document also discloses a kind of method of fixing eye lens blank, and it may further comprise the steps:
